YUTAKI S COMBI

A small heat pump with high performance

A small heat pump with high performance

01. A VERSATILE SYSTEM

Available in two versions: the inverter model provides complete home climate control with hot and cold air and hot water, while the second version produces hot air and water. With a range of power options from 2–6 HP, there’s a model to suit every installation.

02. SPACE-SAVING DESIGN

The new design includes an integrated water tank, reducing the required installation space by up to 70%. The system is available with a choice of a 200 or 260 litre tank.

03. ECO-FRIENDLY EFFICIENCY

High-performance heat pump technology keeps your home at a comfortable temperature even on the coldest days. At the same time, it reduces both domestic power use and CO2 emissions, and is compatible with solar panels.

04. USER-FRIENDLY CONTROLS

The built-in controller has an LCD display and is easy to programme, giving you total control over the system. For even more control, it’s also compatible with wireless thermostats.
